Yes.Yes. Their true (before death) names are irrelevant though because it's a secret a god is NEVER supposed to reveal. If you want to stick closely to lore, the human form name is written in Kun-yoni. The vessel name is the on-yoni translation. In the story, names are important, because spirits can be seriously messed with if an enemy knows their true name (turning them into a phantom and all that), and it's upon risking that name that regalias become blessed regalia. The naming is done by a god to signify the start of a new life as a vessel. Rp-wise, naming their character is the freedom of the rper. Good thing Nagi's not very traditional
